Study sheds new light on why batteries go bad
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought -- and that the benefits of slow draining and charging may have been overestimated. The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.

Buckyballs and diamondoids join forces in tiny electronic gadget
Scientists have married two unconventional forms of carbon -- one shaped like a soccer ball, the other a tiny diamond -- to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.

X-ray laser probes tiny quantum tornadoes in superfluid droplets
An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum 'tornadoes' inside microscopic droplets of supercooled liquid helium -- the first time this formation has been seen at such a tiny scale. The findings by an international research team provide new insight on the strange nanoscale traits of a so-called 'superfluid' state of liquid helium.

Uncertainty gives scientists new confidence in search for novel materials
Scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have found a way to estimate uncertainties in computer calculations that are widely used to speed the search for new materials for industry, electronics, energy, drug design and a host of other applications. The technique, reported in the July 11 issue of Science, should quickly be adopted in studies that produce some 30,000 scientific papers per year.

Scientists use X-rays to look at how DNA protects itself from UV light
The molecular building blocks that make up DNA absorb ultraviolet light so strongly that sunlight should deactivate them -- yet it does not. Now scientists have made detailed observations of a 'relaxation response' that protects these molecules, and the genetic information they encode, from UV damage.

Scientists take first dip into water's mysterious 'no-man's land'
Scientists at the Department of Energy's SLAC National Accelerator Laboratory have made the first structural observations of liquid water at temperatures down to minus 51 degrees Fahrenheit, within an elusive 'no-man's land' where water's strange properties are super-amplified.

Scientists discover potential way to make graphene superconducting
Scientists have discovered a potential way to make graphene -- a single layer of carbon atoms with great promise for future electronics -- superconducting, a state in which it would carry electricity with 100 percent efficiency.
